1 Claim.

li'he present invention has reference to an attachment for use in connection with looms, the primary object of the invention being to provide novel means for automatically throwing the usual shuttle refilling mechanism into operation, when the filling on the quill is practically exhausted.

An important object of the invention is to provide a device of this character which may be readily and easily mounted on a loom, in such a mannor that it will be operated by the contact with the filling of the quill, in such a way that a positive operation of the refilling mechanism will be assured, thereby eliminating mispicks in the cloth during the process of weaving.

A further object of the invention is to provide an attachment of this character which will be completely enclosed in a housing, thereby eliminating the possibility of the device being rendered inoperative by contact with the moving parts of the loom.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described. and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawings:

Figure l is a view illustrating a filling detector constructed in accordance with the invention, as mounted on a loom.

Figure 2 is a plan view of the attachment, showing the attachment as extended into the shuttle of a loom.

Figure 3 is an enlarged plan view of the attachment.

Figure 4 is a side elevational view thereof.

Figure 5 is a sectional View taken longitudinally through the body portion of the device.

Figure 6 is a view taken on line 6-6 of Figure 3.

Referring to the drawings in detail, the frame of a loom is indicated generally by the reference character 5, the frame being of the usual and well known construction.

The device forming the essence of the present invention, includes a body portion or housing indicated by the reference character 6, the same being supported on the loom frame, by means of the bracket '7 which is formed with an elongated opening 8 through which the bolt 9 extends, the bolt 9 passing into an opening formed in the frame of the loom,

The bolt 10 extends from the body portion or housing 6, and passes through the bracket '7, as clearly shown by Figure 1 of the drawings. The body portion or housing 6, is box-like in formation and comprises a lower section 10', and a cover section 11, the cover section being held to the lower section, by means of screws 12.

Slidably mounted within the lower section of the body portion, is a rod 12 that has a right angled end 13 formed with an opening to receive the threaded end 14 of the finger 15, there being provided nuts 16 mounted on the threaded portion of the finger and engaging opposite sides of the right angled end 13 to hold the finger in position, the nuts permitting of adjustment of the finger, towards and away from the quill with which the device is used, thereby regulating the operation of the device and causing the operation of the device when a predetermined amount of filling has been removed from the quill.

The rod 12 is provided with an opening through which the end 17 of the arm 18 extends, the opposite end 19 of the arm extending substantially at right angles, the outer surface thereof being provided with teeth 20.

As shown, the finger is of a length to extend slightly beyond the teeth 20 so that when the filling has become practically exhausted, the finger will act to hold the teeth 26 out of contact with the filling. It follows that the spring 23 will now act to move the arm 18 in a counter-clockwise direction as shown by Figure 5, thereby actuating the rod to cause refilling of the shuttle.

During the normal operation of the loom, the filling of the quill engages the finger 15 and teeth 20, moving the rod 12 and arm 18, rearwardly.

The housing 6 is cut away, providing a space 21 to permit of pivotal movement of the arm 18.

The reference character 22 designates a stop pin that is engaged by the end portion 17 of the arm 18 when the rod 12 and arm 18 are in their normal or inactive positions.

A coiled spring indicated by the reference cha acter 23 engages the right angled end 1'7 of the arm 18, the opposite end of the coiled spring being anchored to the body portion or housing as at 24, the spring operating to actuate the arm 18 in a manner as previously described, when the filling of the quill nears exhaustion.

Mounted within the lower section 10 of the body portion or housing 6 and disposed transversely thereof, is a rod 25 which has an upstanding end portion defining a shoulder 26, which lies in the path of movement of the arm 18, when the arm moves in the direction of the arrow as shown by Figure 5, causing a movement of the rod 25, for purposes to be hereinafter more fully described.

A hook 27 is formed at one end of the rod 25, and is adapted to be hooked to an eye or link formed at one end of the controlling rod of the shuttle refilling mechanism, with the result that when the rod 25 is moved under the action of the arm 18, the controlling rod of the shuttle refilling mechanism is moved, refilling the shuttle.

We claim:

The combination with the lay, shuttle, filling carrier, and shuttle refilling control rod of a loom, the refilling control rod having an offset portion,

of a filling feeler housing having hearings in the ends thereof, a rod. extending through the housing and movable within the bearings, a pin sup ported within the housing, said rod having an opening, a lever having a right angled end extended through the opening, and engaging the pin, said lever engaging within the offset portion of the refilling control rod, a spring for normally urging the right angled end of the lever into engagement with the pin, swinging the outer end of the lever laterally, operating the refilling control rod.
